BOLT-,CUTTER I SPECIFICATION forming' part of Letters Patent No.672,869, dated April 23, 1901.

Application filed November 30, 1900. Serial No. 88,205. LNo model.)

To all whom it may concer-m Beit known thatl, SAMUEL S. BoLsrNGER, acitizen of the United States, residing at Brockway, in the county ofDouglas and State of Oregon,have invented certain new and usefulImprovements in Bolt-Cutters; and I do hereby declare the followingto bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to improvements in bolt or rod cutters. It providesfor readily and eectively severing the bolt or rod, as intimated, andfor securing the proper application of the leverage or power to aid thecutting operation, while simplicity, cheapness, and reduced cost ofmanufacture are obtained.

It consists of the detailed construction, combination, and arrangementof the parts for accomplishing the above ends or objects, substantiallyas hereinafter more fully disclosed, and specically pointed out by theclaims.

In the accompanying drawings, illustrating the preferred form of myinvention, Figure 1 is a broken side elevation thereof, the jaws beingshown open. Fig. 2 is a broken side View witha side plate, 85e.,removed, the jaws being shown closed. Fig. 3 is an edge View of theinvention.

Latitude is allowed herein as to details, as they may be changed orvaried at will without departing from the spirit of my invention and thesame yet remain intact and be protected.,

In carrying out myin vention I pivotbetween suitably connected or boltedtogether guideplates l l two jaws or cutters 2 2, preferably providedwith removable cutters, which when the jaws are open are adapted toreceive between them the 'bolt or rod to be cut, the lower opposedportions or edges of said jaws being rounded, as at 2b, the purpose ofwhich will appear farther on.

The handles or levers 3 3 are each preferably in two parts, the outerend portions 3, constituting cams, eccentrically pivoted between theguide-plates l, with outer convexed or rounded edges 3b, adapted toengage the rounded edges 2l of the jaws or cutters 2, and

inner corresponding edges or faces 2c, adapted to roll or bear upon eachother primarily to exert leverage or power upon and effect the openingand closing of the said cutters or jaws and to secure the maximumcutting action of the latter when first or initiall-y'engaging the boltor rod to be cut when most required and incidentally to facilitate themovement of the parts, dispensing with cogs, &c., therebetween. The jawsor cutters be ing arranged laterally or outside of the camendportions ofthe handles or levers, it will be seen that the latter can be broughttoward each other, thereby effecting the cutting action by said jaws orcutters with the minimum movement of the hand, consequently to thegreatest advantage. This is apparent from the fact that such movement ofsaid handles, whose cam ends engage the longer arms of the cutters orjaws -to bring the cutting edges of said cutters together, is eected bythe contraction of the hand, as in grasping an article and in bringingthe lingers toward the palm, as contradistinguished from the use of thehands in moving the handles or levers apart.

The jaws or cutters and handles are connected up or together by means ofcrossing links 4 to provide for holding them mutually in engagement asthe handles are actuated, said links being slipped upon suitably headedbolts or studs 4i, secured or screwed to said jaws and handles,respectively, the bolts or studs connected to said jaws moving inarcuate or curved slots- 4b in one of the guideplates l to accommodatethe movement of said jaws.

The handles or levers 3 each have their hand-grasping and cam-endedportions halved and toothed or cogged together, as at 5, withadjusting-bolts 5a passing therethrough, to provide for varying theangle of connection therebetween to accordingly accommodate the graspingoff said handles in compensating for wear of the cutting edges or facesof the cutter or jaws.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. A bolt or rod cutter, comprising jaws or cutters, handles or levershaving outer end IOO cam portions adapted to engage said jaws, said jawsor cutters which pass through said 1o and crossing links connecting withsaid jaws slots, substantially as specified. and handles or levers,respectively, substan- In testimony whereof I aiiix my signature tiallyas set forth. in presence of two witnesses.

5 2. A bolt or rod cutter, comprisir, 0f jaws or cutters, guide-platesone having zltzuate or SAMUEL S BOLSINGER curved slots, handles orlevers adapted to Witnesses: engage said jaws or cutters, and crossingE. H. LEMON, links, with the connections between them and 1 GEO. BYRON.
